Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether she has had recent discussions with Ofgem on the potential impact of recent changes in off-peak night rates on Economy 7 electricity tariffs on households which use electricity to heat their homes in comparison with other households.

As the demand for electricity during the night-time period has grown, energy suppliers have had to pay significantly more to purchase that electricity for their customers. In turn, this is reflected in rising night-time rate for time-of-use tariffs

The setting of tariffs, including for peak and off-peak periods for ‘Time-of-Use’ tariffs (such as Economy 7), are a commercial matter for individual energy suppliers.
